Biodegradation Kinetics on The Treatability of 2,4-DCP in An UASB Reactor with Co-Substrate
Subject area: Science,Engineering and Technology · Area of research: Wastewater Treatment
Abstract
Bio mineralization of 2,4 -DCP and kinetic constant for the treatability of the 2,4-DCP has been obtained. Models such as Monod?s, Haldane?s, Contois model, Stover-Kincannon model and Grau-second order multi-component substrate removal model was used to find the kinetic constant. Saturation value constant (KB) and maximum utilization rate (Rmax) were calculated as 7.863 g/L d and 5 g COD/L d representing the substrate removed rate of the microorganism by modified Stover?Kincannon model. Kinetic coefficients Ks=3.26 mg/L and Ki=175.17 mg/L with high correlation coefficient (R2) of 0.998 was obtained by Haldane model. Larger values of Ki, indicate less inhibition effect of 2,4-DCP on the growth of microorganisms.
